I'm using Embarcadero RAD Studio 11.
I'm trying to build an old project on a different computer than it was initially developed. I've managed to overcome some minor issues, but I can't get over this one.
The project has a couple of Units, and I stumbled upon an error described here: Receiving invalid property value
Error reading Image6.OnClick : Invalid Property Value.
I checked the .dfm file as advised (I was not able to find an OnClick property in Image6), and the TButton class missing error emerged afterwards. This issue was mentioned in the comments, but I couldn't find any solution.
The biggest issue is that I can't debug the program to see where exactly the error pops up. Also, I am able to search for the TButton component on the Palette and add it to the units, although I can't find the TButton class on the Palette when I'm in the .cpp file instead of the Designer. I'm not sure if this is the problem, because I can't see the TButton class on the Palette in the working project, either.
Any ideas how I can make the TButton class visible, and run the project?
